Special teams worries for Cowboys

IRVING -- The Cowboys were worried about Eagles returner DeSean Jackson last week in the wild card game, now they have to worry about two for the Vikings game in the divisional round.

Percy Harvin, who led the NFL with two kick returns for touchdowns, averaged 27.5 this season, fourth in the league.

"I'd say he's pretty productive," special teams cooridnator Joe DeCamillis said. "He's an explosive player, he's a downhill runner, he’s very explosive. They do a nice job of spreading the field for him and getting him creases. He will be a real big challenge for us this week."

Darius Reynaud finished ninth in the NFL with a 103 average on punt returns.

"He's a different type of player than Jackson," DeCamillis said. "He's a stronger running back type guy. His body looks like a running back and he breaks tackles."
